Good news - it is back in stock at Amazon - but it requires soldering:

In your case, you would need to disconnect the MP3 module first though... other than that, only a firmware update to v47 is required on the LS 3 side.

The MP3 module can be put to sleep. Maybe both can be used in the same time. I would try it, but got no MIDI things here at all.

I will try that. Did you already add the |mp3sleep command to the LS3 RSX ROM?

Two more shipping on Monday... picture for the owner.

For the time being, I have exactly ONE more DELUXE VERSION to sell (MP3 + RTC + SP0256-AL2), then I am out of parts - see 2nd picture.

PM if you want it! This is going to be the last one until November or so. Especially SP0256-AL2's are hard to get and cost me a fortune (~ 30 $ each).

30$ ?  :o


What about that: https://www.ebay.com/itm/1PCS-VOICE-SYNTHESIZER-IC-MICROCHIP-DIP-28-SP0256A-AL2/162779229313?epid=16010546217&hash=item25e665ec81:g:MkgAAOSwk1haHjqY
They are many other links about tham for less than 5$ inculding shipping fees.

Great find! I haven't seen them this cheap for a long time.

No, not a great find - I tried them and they are fake!!
I couldn't believe this story until I could verify it myself, but it IS true: they don't work:
http://www.smbaker.com/counterfeitfakejustplainbad-sp0256a-al2-chips
From this link, wrt to the Microchip chips:
Quote
The second set of bad chipsI decided to order more (Fool me once, shame on you. Fool me twice, shame on me). This time I chose a different seller, with chips that had a different manufacturer printed on them.

Here’s a picture:

Unlike the previous ones, these ones don’t output any speech at all. There is some noise that comes out of the output pin, and that noise varies according to what is on the address and data buses, even when the chip select input is not triggered. So it kinda makes annoying noise all the time.  It also glitched my RC2014 so that it wouldn’t run (probably by outputting signals to the address, data, or control buses).

I suspect these are just some random 28-pin IC that someone reprinted. I suppose it would be an interested exercise to apply to signals to the fake chips and use a logic analyzer to try to figure out what it’s actually doing, and determine that the chips actually are.

 Also:
https://www.eevblog.com/forum/projects/where-to-buy-an-sp0256-al2-speech-synthesizer-chip/
The only reliable source I have is this one - they are genuine GI and work.

If you don't believe it, buy one of the Ebay ones yourself and be amazed - they don't do anything. They don't even get warm.

2014 date code is highly suspicious !
Repackaged ones, emulated ones ?
Who knows ?

Indeed. They are fake. Don't buy them. See stories above. I tried them!

Time to make our own fake, emulating them on a STM32 or like.
I think there is C source and ROM dump somewhere.

Oops, didn't notice the dodgy date code, although I'd read that as Week 14, 2002 (which would still be questionable).

2004 was 15 years ago... Microchip produced many IC clones from GI as AY3-89xx too. (And works fine as I know)
I do not see the problem. It they are fakes or not OK for your usage, you just have to open ark a refund of open a PayPal dispute to got your money back.
When you see the quantities sold and no negative feedbacks on their eBay profile, I imagine that are OK or peoples are dumbs.  :-\

Is this better (it came from China too) ?

As I have read on forums, most IC sold is USA came from China too, but more expensives. So, how looks your 30$ versions?

The $30 dollar ones are from GI and have a 1986 date code. I have one here.

I think the fakes I've read about weren't an AY clone fake, just some random chip with the same pin count, they don't function at all.Also, thanks to evilbays biased tactics, as soon as you open a case you can no longer give any feedback which could explain the lack of negativefeedback.

I have not ordered SPO-2 IC, but some other video and sound chips w/o any issues for really low cost.
Now, I don't said to buy 10pcs of them and pray... But I will not buy 1pcs for 30$ too.  ;D

Selling relabeled wrong IC is a 100% fail tacticle through eBay as sellers can't won any money with the PayPal protection.
Next, I have currently into my eBay an item (game box) refunt because damaged and I can left a feedback on it if I wish.

Microchip IS GI semicoductor unit spinout. These are not clones.

ToTO saying it for the third time, hope the message gets through - I BOUGHT TWO SETS OF MICROCHIP SP0256-AL2 CHIPS FROM THE EXACT EBAY SELLER YOU QUOTED AND THEY ARE FAKES AND DO NOT WORK.

Having said that, I AM interested in an inexpensive source of WORKING GI SP0256-AL2 chips. Please post your links here.
I find it weird that you guys just ignored what was quoted above regarding the Microchip GI SP0256-AL2 chips. I am not saying there are NO working Microchip SP0's, but I don't have a source. My source is 30 $.

If anybody has a reliable source of working Microchip SP0256-AL2 I want to know the source and then we can table the discussion and go back to the facts.
